You can order it from Varmilo. $131 for the keyboard. Shipping for me was $24 with UPS (no customs or anything like that, thats included), but that was for a numpad so maybe slightly more for this. There you could also choose precisely what case, switches, leds and keycaps (they can even do your own design) you want.
If you want rgb, I'd hold out a couple of months more. They just released their "Rainbow" keyboards, but only with a white case. Seems reasonable they'll add that option to the others soon.
